Serum biochemical markers of PCOS were assayed during the early follicular phase of the menstrual cycle in menstruating patients and controls, and on a randomly selected day in amenorrheic patients. <jats:italic>Results<\/jats:italic>: When assessing the delicate structure of the ovary in virgin patients, 3D\u2010TRS was convenient, accurate, specific, sensitive, and more reliable overall than transabdominal ultrasonography. Ovarian stromal area and S\/A ratio were significantly greater in patients with PCOS than in controls, and also in the patients who had ultrasonically diagnosed polycystic ovaries without clinical or biochemical evidence of PCOS. The S\/A ratio was the studied variable most significantly correlated with androgen levels. <jats:italic>Conclusions<\/jats:italic>: These findings indicated that, in adolescent patients, 3D\u2010TRS combined with transabdominal ultrasonography can improve the precision of the diagnosis of PCOS. The S\/A ratio may become the ultrasonographic diagnostic marker for PCOS.<\/jats:p>","DOI":"10.1016\/j.ijgo.2007.02.024","type":"journal-article","created":{"date-parts":[[2007,4,25]],"date-time":"2007-04-25T11:10:09Z","timestamp":1177499409000},"page":"34-38","source":"Crossref","is-referenced-by-count":23,"title":["Three\u2010dimensional transrectal ultrasonography in adolescent patients with polycystic ovarian syndrome"],"prefix":"10.1002","volume":"98","author":[{"given":"Li","family":"Sun","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qingzhao","family":"Fu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,4,24]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(15)30642-6"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2265.1989.tb00457.x"},{"key":"e_1_2_5_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(88)91612-1"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.3109\/09513598709082702"},{"key":"e_1_2_5_6_2","doi-asserted-by":"publisher","DOI":"10.3109\/09513599309152512"},{"key":"e_1_2_5_7_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-0705.1995.06030164.x"},{"key":"e_1_2_5_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejrad.2004.03.024"},{"key":"e_1_2_5_9_2","doi-asserted-by":"publisher","DOI":"10.1002\/uog.110"},{"key":"e_1_2_5_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(85)92552-8"},{"key":"e_1_2_5_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0301-5629(00)00219-2"},{"key":"e_1_2_5_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0015-0282(98)00092-2"},{"key":"e_1_2_5_13_2","doi-asserted-by":"publisher","DOI":"10.1259\/bjr.75.889.750009"},{"key":"e_1_2_5_14_2","doi-asserted-by":"publisher","DOI":"10.1093\/humrep\/del161"},{"key":"e_1_2_5_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.gyobfe.2006.02.017"},{"key":"e_1_2_5_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.fertnstert.2006.04.015"},{"key":"e_1_2_5_17_2","doi-asserted-by":"publisher","DOI":"10.1196\/annals.1290.006"},{"issue":"3","key":"e_1_2_5_18_2","doi-asserted-by":"crossref","first-page":"267","DOI":"10.1055\/s-2003-43304","article-title":"Diagnostic criteria in polycystic ovary syndrome","volume":"21","author":"Legro R.S.","year":"2003","journal-title":"Semin Reprod Med"},{"issue":"11","key":"e_1_2_5_19_2","first-page":"950","article-title":"Endorectal sonography in gynecology: usefulness and diagnostic accuracy","volume":"32","author":"Crequat J.","year":"2004","journal-title":"Gynecol Obstet Fertil"},{"key":"e_1_2_5_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0015-0282(01)01919-7"},{"key":"e_1_2_5_21_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0015-0282(02)04801-X"},{"key":"e_1_2_5_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.fertnstert.2005.07.1279"},{"key":"e_1_2_5_23_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0015-0282(16)55797-5"},{"key":"e_1_2_5_24_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0950-351X(96)80099-1"},{"key":"e_1_2_5_25_2","doi-asserted-by":"crossref","unstructured":"Fleischman A Mansfield J.
